Using ruby 1.9.2, rails3.1.0, Why am I getting an error when I try to generate a scaffold.

Question

Basically, When I try to generate a scaffold I am getting this error no such file to load -- openssl (LoadError) . The error is coming from

.rvm/gems/ruby-1.9.2-p290@rails310/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:240:in `block in require'

Not sure why this is happening. Here is the full error:

Answer 1

OK so what I ended up doing is this.

• uninstalled all version of ruby from rvm
• deleted all of the gemsets from rvm
• $ rvm pkg install openssl
• $ rvm pkg install zlib
• $ rvm install 1.9.2 --with-openssl-dir=$HOME/.rvm/usr --with-zlib-dir=$rvm_path/usr
• reinstalled rails in a gemset

Everything works fine after that.

You should be able to do something like this: (forgive the fact that there may be errors in my paths and I'm not on my linux box)

cd to ~.rvm/src/ruby-1.9.2-p290/ext/openssl
ruby extconf.rb
make
make install

Basically, just cd to the gem's source directory for your particular ruby version and rebuild/install this.

You will not need to rebuild ruby, this has been a common problem.
